The formula for calculating the volume of any uniform prism is based on the principle that the volume can be determined by multiplying the area of the cross-section by the length of the prism. A uniform prism maintains a consistent cross-sectional shape along its length, so no matter where you take that cross-section, the area remains the same.

By using the formula that states volume equals the area of the cross-section multiplied by the length, you can accurately determine the total volume of any prism, whether it's triangular, rectangular, or any other polygonal shape. This method effectively captures how much space the prism occupies.

Other formulas provided relate specifically to certain geometrical shapes. For example, the formula for the volume of a cylinder involves the area of a circle (which is represented in terms of πr²) multiplied by its height. The formula for a rectangular prism—length × width × height—applies to rectangular shapes specifically. While these formulas can yield the volume for certain types of shapes under specific conditions, they do not universally apply to all uniform prisms as the first formula does. Thus, the correct choice pertains directly to the general case for any uniform prism.
